Coral Earring
This lure is in Twilight Princess and can only be obtained after recieving Ashei's picture of the monster holding a Red fish. After you get the picture, go to Kakariko Village and into the graveyard. Go to where you got the Zora Armor and you will meet Prince Ralis. Since he only knew how to catch the fish in the picture, known as a Reekfish, he will tell you the secret to catching one. It's all in the coral, but not just any coral, only coral that grows in rare places. Luckily, Ralis has some as earrings and even more coinsidently, they are in the shape of fish hooks! Ralis will give you one and it will now be your new lure for your fishing pole.
